9322705 Swift Research conducted by this award is a component of the 1994 U.S./Canada Arctic Ocean Section (AOS). The AOS is a collaborative effort with Canada that involves approximately 60 scientists participating on a Canadian and a U.S. icebreaker during a 55-day field program in the summer of 1994. The AOS is under the auspices of the Arctic Systems Science (ARCSS) Global Change Research Program and research is jointly sponsored by the Division of Ocean Sciences, the Office of Polar Programs and Office of Naval Research (ONR). Data collected should be relevant to improving our understanding of how the Arctic is an indicator of changing global climate conditions and how it affects the physical, chemical, and biological features of the more temperate oceans and regions. This project encompasses a service and research program. The Oceanographic Data Facility (ODF) at the Scripps Institution of Oceanography will conduct a detailed hydrographic survey consisting of about 100 precision temperature, conductivity, oxygen, and nutrient profiles at approximately 30 km intervals along the cruise track. Resulting data will be shared with all participants. Swift will use the hydrography data to focus on a study of the origin and circulation of the intermediate and deep waters of the Arctic Ocean and nearby seas. Parameters to be determined are the surface-to-bottom distributions and sources of the physical and chemical characteristics, and the location, origin, and the structure of sub-surface boundary currents. Information thus obtained will augment other studies during the AOS and will contribute to studies of the response of the regimes to environmental forcing. ***

9322705斯威夫特研究进行了这项奖励是一个组成部分，1994年美国/加拿大北冰洋科。 AOS是与加拿大合作的一项努力，大约有60名科学家参加了1994年夏天在一艘加拿大和一艘美国破冰船上进行的为期55天的实地项目。 AOS是在北极系统科学（ARCSS）全球变化研究计划的主持下进行的，研究由海洋科学部，极地计划办公室和海军研究办公室（ONR）联合赞助。 收集的数据应有助于我们更好地了解北极如何成为全球气候条件变化的指标，以及它如何影响更温和的海洋和区域的物理，化学和生物特征。 该项目包括一个服务和研究计划。 斯克里普斯海洋学研究所的海洋学数据设施将进行详细的水文调查，包括沿巡航轨迹沿着约30公里每隔约100个精确的温度、传导性、氧气和营养物剖面。 所产生的数据将与所有参与者共享。 斯威夫特将利用水文地理数据，重点研究北冰洋和附近海域的中层和深层沃茨的起源和环流。 待确定的参数是物理和化学特性的表面到底部的分布和来源，以及次表面边界流的位置、来源和结构。 由此获得的信息将补充AOS期间的其他研究，并将有助于研究这些机制对环境强迫的反应。 ***
